Texas regulators are weighing emergency curtailment requirements for an expanding AI campus operated by Crusoe and Ensign Infrastructure, in what amounts to one of the first real tests of the state’s new framework governing large electric loads colocated behind existing generation facilities.
The Project at Issue
The application proposes adding a 260 MW facility called “Crusoe Load 2” behind the 265.5 MW Goodnight 1 wind farm in Armstrong County. Combined with the previously approved “Crusoe Load 1,” the campus would place 525.5 MW of behind-the-meter data center load on Goodnight 1’s existing point of interconnection (POI). “Behind-the-meter” here means both data centers sit on the generator’s side of its connection to the ERCOT grid, drawing power before it reaches the broader market.
What Regulators Are Proposing
Staff at the Public Utility Commission of Texas (PUCT) recommended approving the application, but subject to the same six operating conditions imposed earlier on Crusoe Load 1. The central condition requires Crusoe Load 2 to curtail within 30 minutes whenever ERCOT determines Goodnight 1’s output is needed to address a transmission emergency or an Energy Emergency Alert. If the facility later demonstrates it can respond faster, that window could shrink to 10 minutes. The staff position is grounded in PUCT Rule 25.205, adopted to implement Senate Bill 6, which establishes the review process for net-metering arrangements between generators and colocated large loads.
Ensign’s Counter-Argument
Ensign does not dispute the Commission’s authority to set reliability conditions, but argues the proposed requirements go beyond what state law authorizes for this specific project. Its reasoning is straightforward: Crusoe Load 1 already carries an obligation to curtail up to 265.5 MW during emergencies, which fully restores Goodnight 1’s capacity to the ERCOT market. Requiring Crusoe Load 2 to curtail as well, Ensign says, addresses a reliability gap that does not exist. The company also points to ERCOT studies finding no thermal or voltage violations and no need for new transmission infrastructure to support the expansion.
PUCT staff rejects this framing, arguing the shared POI governs the analysis rather than the sequence in which projects were approved behind it. ERCOT takes a similar position and notes that the developer could have avoided this review entirely by building a separate interconnection for the expansion.
Why the Outcome Matters Beyond This Case
Chris Talley, co-founder of Interconnection.fyi, told Data Center Knowledge that the Commission’s decision could set a significant precedent for how AI campuses are designed across Texas. If ERCOT’s position prevails, colocating any load with a qualifying standalone generator would effectively expose the entire load to full curtailment risk during emergencies, regardless of how small the generator is relative to the facility.
Talley raised a hypothetical from Ensign’s own brief: whether a 1 GW data center colocated with a 50 MW generator could be required to shut down the full 1 GW load in an emergency. Under ERCOT’s current argument, the answer would be yes.
- Developers relying on behind-the-meter colocation may need to size on-site backup generation to cover their entire load if they want to manage curtailment risk.
- A separate pending application involving Amazon and the Comanche Peak nuclear plant represents a different model, where the data center would shift to customer-owned backup power during emergencies while returning the plant’s output to the grid.
- Talley noted that ERCOT’s position is not simply opposition to data center growth, but reflects a difficult tradeoff between enabling new load and preserving grid reliability.
A final Commission ruling has not yet been issued. The proceeding will be closely watched by developers planning large AI infrastructure projects across Texas.
